Detailed Description

In order to make the technical solutions of the present invention better understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships that are based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, rather than to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to the accompanying drawings 1 to 7, the utility model relates to a rotation adjusting device for a seat waist pillow, which comprises a second support 4, a first support 5, a waist pillow 1 and a seat back plate 2, wherein one end of the second support 4 is fixedly connected with one side of the seat back plate 2, the other end is fixedly connected with a rotation adjusting mechanism 3, one end of the first support 5 is fixedly connected with one side of the waist pillow 1, and the other side is rotatably connected with the rotation adjusting mechanism 3;

the rotation adjusting mechanism 3 comprises a mounting plate 6 and a protection plate 9, the mounting plate 6 is fixedly connected with a second support 4, one end of the second support 4 fixed with the mounting plate 6 is provided with a sliding groove 16 extending outwards and a containing groove 17 communicated with the sliding groove 16, a rack block 10 is arranged in the sliding groove 16 in a sliding mode, a spring 11 is arranged in the containing groove 17, the spring 11 abuts against and is movably connected with the rack block 10, a boss 18 is arranged on the end face of the rack block 10, one side, far away from the spring 11, of the rack block 10 is in toothed connection with a gear block 7, one side, far away from the rack block 10, of the gear block 7 is provided with a groove 14, an axle boss 15 is arranged on the end face of the gear block 7, a clutch 8 is arranged on the axle boss 15, one side of the clutch 8 is provided with a protruding portion 12, the other side of the clutch 8 is provided with an abutting portion 13 protruding outwards, the abutting portion 13 of the clutch 8 is arranged in the groove of the gear block 7, the abutting portion 12 of the clutch 8 is arranged in the groove 18 of the gear block 10, the protruding portion 12 of the clutch 8 is used for extruding and pushing the gear block 10 so that the gear block 10 is separated from the gear block 7, and the protection plate 9 is fixedly connected with the mounting plate 6.

When the gear block 7 is engaged with the rack block 10, the rack of the gear block 7 is tilted counterclockwise and the rack block 10 cannot rotate, so that the gear block 7 can only rotate clockwise.
